An integrated fuzzy sustainable supplier evaluation and selection framework for green supply chains in reverse logistics.

Green supply chain management considers the environmental effects of all activities related to the supply chain, from obtaining raw materials to the final delivery of finished goods. Selecting the right supplier is a critical decision in green supply chain management. We propose a fuzzy green supplier selection model for sustainable supply chains in reverse logistics.

Inter- and intra-examiner agreement of three classification systems of gingival recession.

Background: Several classifications have been proposed for gingival recession defects. Correct diagnosis of the type of gingival recession is necessary for proper treatment planning and assessment of the prognosis. Considering the existing uncertainty regarding the reliability of different classification systems available for gingival recession and their shortcomings, this study sought to assess the reproducibility and reliability of accuracy of three available classifications (Cairo, Mahajan and Miller's classification systems) for gingival recession.

The effect of endotracheal tube cuff pressure control on postextubation throat pain in orthognathic surgeries: a randomized double-blind controlled clinical trial.

Pain in the throat after extubation is one of the most common complaints after maxillofacial operations under general anaesthesia. We have evaluated the amount of pain after extubation when we controlled the pressure in the endotracheal cuff during operation by analysing the records of 43 patients who had maxillofacial operations under general anaesthesia. In the study group (n=20) the cuff pressure of the endotracheal tube was adjusted using a pressure gauge at the beginning of intubation and every hour during operation.
